Joel Pineiro, SP, Los Angeles Angels of Anaheim

Pineiro's stock sinking upward?

Pineiro (oblique) will have missed nearly two months by the time he takes the mound for the Halos this weekend versus the Tampa Bay Rays. After some simulated games and a rehab start for Advanced Class A Rancho Cucamonga this past weekend, he should be good to go.

Pineiro has experienced above-average ground-ball success this season, although his rate isn't quite as pronounced as it was last season, with the St. Louis Cardinals. The combination of a regression to his career norms in BB/9 and HR/9, although still more than acceptable, point to the areas that have contributed to his more ordinary 4.18 ERA and 1.31 WHIP.

Pineiro is no K artist, but he remains serviceable. He'll get a few starts to close things out. Maybe you'll think that it's best to avoid the right-hander against a deep Tampa club. If his sinkerball is on, he'll be fine.

Shallow mixed: Pass
